Positive reinforcement training to enhance the voluntary movement of group-housed chimpanzees within their enclosure

Positive reinforcement techniques are described and were applied to train groups of chimpanzees to move voluntarily into the indoor portions of their enclosures at the request of trainers and to be briefly restricted to those areas. ... Females required significantly...

Response of captive Barbados green monkeys (Cercopithecus aethiops sabeus) to a variety of enrichment devices

Response to several toys and foraging devices were tested. Single-housed. subjects interacted more frequently with items which are transparent.

Enlarging chimpanzee social groups: The behavioral course of introductions

All 42 introductions of chimpanzees (aged 3-43 years) in already established groups were successful. New group members were first introduced behind mesh fencing. Subsequent full physical contact did not further increase agonism. Stereotyped rocking declined in newly integrated individuals.

Behavior and salivary cortisol in gorillas housed in an all male group

Group-housed male gorillas were trained to voluntarily chew on the cotton plugs then return them to the caretaker ... Further analysis of these data may provide a better understanding of how the gorillas are perceiving and adapting to their physical...

Please don’t touch, we’re being enriched! In: Proceedings of the International Conference on Environmental Enrichment

Enrichment often involves manipulation of animals' lives. However, non-interference in their social lives is an important form of environmental enrichment for chimpanzees. Rather than locking the chimpanzees into their indoor cages every evening, an average of 17 hours a day...

Behavioral effects of simple manipulable environmental enrichment on pair-housed juvenile macaques (Macaca nemestrina)

The teddy bear was preferred as a manipulable toy over the pink teething ring and the green teething ring. Toy use declined with time, indicating that rotation of toys, at least in the short term, may increase use.
